Categorizing search terms

ABSTRACT

A system and method are disclosed for categorizing search terms. The system accesses search history for the search terms. The system also categorizes each of the search terms based on the number of times that the respective search term appears in the search history. If the number of times the search term appears in the search history exceeds a first threshold, a search result of the search term is determined and the search term is categorized as a type that is provided for registration to a user with recognized association with the search term or a type that is excluded from registration, where the categorizing based on a ratio of a number of times the search result was selected subsequent to receiving the search term to the number of times that the search term appears in the search history.

BACKGROUND

The subject technology generally relates to categorizing search terms.

A uniform resource locator (“URL”) is may be assembled in a way to convey a message or an association. Registration of URL may be obtained on a first come first serve basis, where the first user to select a unique URL obtains the right to use the URL. Sometimes, the first user to come up with a URL has little or no association with the message conveyed by the selected URL.

SUMMARY

The disclosed subject matter relates to a computer-implemented method including accessing search history for one or more search terms, wherein the search history comprises prior user search terms. The method further includes categorizing each of the one or more search terms based on the determined number of times the respective search term appears in the search history. For each of the one or more search terms, the categorizing includes in a case where the number of times that the search term appears in the search history exceeds a first threshold value, identifying, from the search history, a search result of the search term, and categorizing, the search term as a type that is provided for registration to a user with recognized association with the search term or a type that is excluded from registration, wherein the categorizing is based on a ratio of a number of times the search result was selected subsequent to receiving the search term to the number of times that the search term appears in the search history.

These and other aspects can include one or more of the following features. For each of the one or more search terms, the categorizing further includes, in a case where the number of times that the search term appears in the search history does not exceed a second threshold value, categorizing the search term as a type that can be reserved on a first come first serve basis. For each of the one or more search terms, categorizing the respective search term may further include in a case where the number of times that the search term appears in the search history does not exceed the first threshold value and exceeds the second threshold value, the search term is categorized as a type that can be reserved with additional verification of association with the search term. The search term may be categorized as a type that is provided for registration to a user with recognized association with the search term if the ratio of the number of times the search result was selected subsequent to receiving the search term to the number of times that the search term appears in the search history exceeds a third threshold value. The search term may be categorized as a type that is excluded from registration if the ratio of the number of times the search result was selected subsequent to receiving the search term to the number of times that the search term appears in the search history does not exceed the third threshold value. The search result may include a character string for a uniform resource locator, where the character string includes the search term.

For each of the one or more search terms, categorizing the respective search term may further include determining if the search term is a restricted term, and designating the search term as a term that is excluded from registration if the search term is a restricted term. A restricted term may be a trademark.

Accessing the search history for search terms and categorizing the search terms may each be performed on a periodic basis. The search terms may be periodically categorized based on one or more user inputs.

The search term may be a single term. The search term may also be a composite term, where the composite term includes two or more terms. The method may further include filtering the search terms for a term corresponding to a user selected search term, and designating registration requirement of the user selected search term based on a type of the corresponding term. The method may further include determining one or more locales where the prior user action was performed by users.

DETAILED DESCRIPTION

The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be clear and apparent to those skilled in the art that the subject technology is not limited to the specific details set forth herein and may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology.

In accordance with the subject technology, a system and a method for categorizing search terms are provided. The subject technology has access to search history for prior user search terms. In one example, the search history is stored on a server's database and contains information regarding the prior user search terms, such as the number of times a particular search term was previously entered. A search term may include characters, numbers, symbols, etc. Furthermore, a search term may be a single term (e.g., “john”), or a composite term (e.g., “johnwater”). A search term may be a term that was previously entered into a search engine.

The subject technology accesses a search history that contains prior user search terms, and categorizes a prior user search term as a generic term, e.g., which is excluded from registration, a top term, which can be registered by a user with recognized association with the term, a search term that is available on a first come first serve basis, or a search term that is available pending additional verification of user association with the search term based on a number of times that the search term appears in the search history. A user seeking to obtain a URL that includes the search term may be restricted from obtaining the URL, allowed to obtain the URL on a first come first serve basis, or required to provide verification of association with the search term in order to obtain the URL.

If the number of times that a search term appears in the search history exceeds a threshold value, the search term may be categorized as a generic term, and a URL containing the search term is excluded from registration. Alternatively, if the number of times that the search term appears in the search history does not exceed the threshold value, the search term may be categorized a top term, where the search term is recognized to be associated with a user or an entity and is provided for registration to the user or entity that is recognized to be associated with the search term.

One example method for determining whether a search term is a top term or a generic term depends on whether user actions subsequent to entering the search term on different occasions are consistent. For example, if a majority of prior user actions subsequent to entering the search term “john” consist selecting www.johndoe.com, then “john” is considered to be a top term and would be reserved for johndoe.com. Alternatively, if there is no consistent prior user action subsequent to entering the search term “john,” then the search term “john” may be considered as a generic term.

Some high frequency search terms may be associated with a user or entity by users within one local population, and may be considered to a generic term that is not associated with any user or entity by users within a second local population. In one example, the search term “john” may consistently be associated with johndoe.com by users within the United States, but may not be associated with any user or entity by users in Germany. In this scenario, whether the search term “john” is considered a top term or a generic term may depend on popularity of the term “john” with respect to the local population of United States and Germany respectively. Additionally, the population size of the United States vs. the population size of Germany may also determine whether the term “john” is considered as a top term or a generic term.

If the number of times that a search term appears in the search history does not exceed a threshold value, the search term may be considered to be non-generic and not belonging to any user or entity. In this case, any user or entity may reserve the search term on a first come first serve basis. Furthermore, if the number of times that a search term appears in the search history exceeds the threshold value allowed for the search term to be reserved on a first come first serve basis but does not exceed the threshold value allowed for the search term is considered to be either a generic term or a top term may be considered as a semi-restricted term, the search term may be obtained if a user or entity can prove a legitimate association with the search term.

A composite search term (e.g., “johndoe” or “johnwater”) is analyzed in its entirety. For example, if the number of times johndoe appears in the search history exceeds a threshold value, then johndoe is categorized as either a generic term or a top term. However categorization of johndoe does not affect the categorization of john or doe.

The subject technology may restrict registration of certain search terms regardless of the number of times they appear in the search history. In one example, the subject technology has access to a database that contains trademarks, and filters the trademark database for search terms. In general, if a search term is determined to be a trademark, the search term is excluded from registration unless the user can prove that the user is authorized to use the trademark as part of the user's URL.

The subject technology may periodically update the search terms to ensure each search term is accurately categorized. In one example, the subject technology may periodically filter the search history to determine the number of times each of the search terms appear in the search history, and categorize the search terms, where each search term is categorized into different categories based on the algorithms described herein. In another example, categorization of a search term may be modified by developers or other users who are authorized to modify the search term's category.

FIG. 1 illustrates an example network environment for categorizing search terms. A network environment 100 includes a number of electronic devices 102, 104, and 106 communicably connected to a server 108 by a network 110. Server 108 includes a processing device 112 and a data store 114. Processing device 112 executes computer instructions stored in data store 114, for example, to categorize search terms based on a number of times that the search terms appear in a search history. The search history may be stored in stored in the data store or another data base that is accessible to server 108.

In some example aspects, each of the electronic devices 102, 104, or 106 may include any machine that can transmit a user search term to server 108. Electronic devices 102, 104, and 106 can be mobile devices (e.g., smartphones, tablet computers, PDAs, and laptop computers), portable media players, desktop computers or other appropriate computing devices. In the example of FIG. 1, electronic device 102 is depicted as a smartphone, electronic device 104 is depicted as a desktop computer, and electronic device 106 is depicted as a tablet computer.

An application (e.g., web browsing application, electronic messaging application, etc.) running on electronic device 102, 104, or 106 may provide an interface for a user to enter a search term. Electronic device 102, 104, or 106 may transmit the search term to server 108. Electronic device 102, 104, or 106 may also transmit data corresponding to user actions related to the search terms (e.g., a user's action subsequent to entering the search term, etc.) to server 108 via network 110.

Server 108 may be any system or device having a processor, memory, and communications capability for providing messaging recommendations for electronic messaging. Server 108 may be a single computing device such as a computer server. Server 108 may also represent more than one computing device working together to perform the actions of a server computer.

Server 108 includes a processing device 112 and a data store 114. Processing device 112 executes computer instructions stored in a computer-readable medium, for example, to categorize search terms based on a number of times that the search terms appear in a search history and to provide a search term corresponding to a user designated term to electronic device 102, 104, or 106.

Server 108 accesses search history, which contains prior user search terms to determines a number of times that a search term appears in the search history and categorizes the search term based on the determined number of times that the search term appears in the search history. In a case where the number of times that the search term appears in the search history exceeds a first threshold value, categorizing the search term includes determining, a search result of the search term, and categorizing the search term as a type that is provided for registration to a user with recognized association with the search term or a type that is excluded from registration based on a ratio of a number of times the search result was selected subsequent to receiving the search term to the number of times that the search term appears in the search history. In a case where the number of times that the search term appears in the search history does not exceed a second threshold value, the search term is categorized as a type that can be reserved on a first come first serve basis.

Server 108 may receive a user-designated search term. Server 108 may filter the search terms for a search term corresponding to the user-designated search term. Server 108 may, based on type of the search term, allow, reject, or restrict registration of a domain name that includes the user-designated search term.

Network 110 can include, for example, any one or more of a cellular network, a satellite network, a personal area network (PAN), a local area network (LAN), a wide area network (WAN), a broadband network (BBN), the Internet, and the like. Further, the network 108 can include, but is not limited to, any one or more of the following network topologies, including a bus network, a star network, a ring network, a mesh network, a star-bus network, tree or hierarchical network, and the like.

FIG. 2 illustrates an example process 200 for categorizing search terms. Although the operations in process 200 are shown in a particular order, certain operations may be performed in different orders or at the same time.

In block 210, server 108 accesses search history for one or more search terms, where the search history includes prior user search terms. In one example, the search history is stored in a database that is accessible to server 108. In another example, the search history is stored in data store 114. A search term may be a single term (e.g., “john,” “water,” etc.). Alternatively, the search term may be a composite term (e.g., “johnwater,” etc.). Server 108 may also determine a number of times that the search terms appear in the search history.

In block S220, server 108 determines, for each of the one or more search terms, whether the number of times the respective search term appears in the search history exceeds a first threshold value. If the number of times that the search term appears in the search history exceeds the first threshold value, the process proceeds to block S225 and server 108 identifies, from the search history the search history, a search result of the search term. In one example, a search result of the search term “johndoe” is a link for “johndoe.com.” Server 108 may also determine a number of times a prior user action was performed subsequent to receiving a search result based on the search term. In one example, a prior user action consists selecting a uniform resource locator that includes the search term.

In block S230, server 108 categorizes the search term as a type that is provided for registration to a user with recognized association with the search term or a type that is excluded from registration, wherein the categorizing is based on a ratio of a number of times the search result was selected subsequent to receiving the search term to the number of times that the search term appears in the search history. Server 108 categorizes the search term as a type that is provided for registration to a user with recognized association with the search term if the number of times a search result containing the search term was selected subsequent to receiving a search result based on the search term to the number of times the search term appears in the search history exceeds a third threshold value. In another example, server 108 categorizes the search term as a type that is excluded from registration if the ratio of the number of times the search result was selected subsequent to receiving the search term to the number of times that the search term appears in the search history does not exceed the third threshold value. In another example, if multiple search results are associated with the search term, determining whether the search term is a type that is excluded from registration or a type that is provided for registration to a user with recognized association with the search term is be based on the ratio of the number of times the most selected search results was selected subsequent to receiving the search term to the number of times the search term appears in the search history. In a further example, if multiple search results are associated with the search term, determining whether the search term is a type that is excluded from registration or a type that is provided for registration to a user with a recognized association with the search term is based on a ratio of the number of times one of the selected search results was selected subsequent to receiving the search term to the number of times one or more different search results were selected subsequent to receiving the search term.

In a further example, if multiple search results are associated with the search term, determining whether the search term is a type that is excluded from registration or a type that is provided for registration to a user with recognized association with the search term is based on the number of search results that are associated with the search term. For example, if the number of different search results that are associated with the search term exceeds a certain threshold value, then the search term is categorized as a type that is excluded from registration. However, if the number of different search results that are associated with the search term does not exceed a certain threshold value, then the search term is categorized as a type that can be registered by a user with recognized association with the search term.

In another aspect of the subject technology, server 108 determines geographical locations of users that performed actions (e.g., selecting a uniform resource locator that includes the search term, etc.) subsequent to receiving a search result based on the search term. In one example, information related to user geographical location is stored in the search history. Server 108 also determines one or more locales where the prior user action had been performed by users. In one example, each locale is associated with a particular geographical location (e.g., the United States, Germany) that members of the locale reside in. For each locale, server 108 categorizes the search term as a type that is provided for registration to a user with recognized association with the search term if the ratio of the number of times the search result was selected by users in the locale subsequent to receiving the search term to the number of times that the search term appears in the search history exceeds a fourth threshold value. For each locale, server 108 categorizes the search term as a type that is excluded from registration if the ratio of the number of times the search result was selected by users of the locale subsequent to receiving the search term to the number of times that the search term appears in the search history does not exceed the third threshold value.

Alternatively, if the number of times that the search term appears in the search history does not exceed the first threshold value, the process proceeds to block S235 and server 108 determines if the number of times that the search term appears in the search history exceeds a second threshold value. If the number of times that the search term appears in the search data does not exceed the second threshold value, the process proceeds to block S240, and server 108 categorizes the search term as a type that can be reserved on a first come first serve basis. Alternatively, if the number of times that the search term appears in the search history exceeds the second threshold value, and does not exceed the first threshold value, the process proceeds to block S245, where server 108 categorizes the search term as a type that can be reserved with additional verification of association.

Server 108 may also determine if the search term is a restricted term. In one example, a restricted term is a trademark. In another example, a restricted term includes a preposition, a noun, a verb, an adverb, an adjective, or a term that is frequently used to construct a sentence. Upon determining that the search term is a restricted term, server 108 designates the search term as a term that is excluded from registration.

Server 108, upon receipt of a user-selected term the user wishes to register as part of an URL, may filter the search terms for a search term that matches the user-selected term. In one example, a user-selected term matches a search term if the user-selected search term is identical to the search term. In another example, a user-selected term matches a search term if a portion of the user-selected search term is identical to a portion of one of the search terms. Server 108, upon obtaining a search term that matches the user-selected term, may designate registration requirement of the user selected term based on the type of the matching search term. Server 108 may provide a notification to the user, to notify the user requirements for obtaining a URL assembled with the user-selected term.

FIG. 3 is an example illustration for organizing search terms based on their respective categorization. As shown in FIG. 3, the search terms are partitioned into four areas. Area 305 contains search terms that may be registered one a first come first serve basis. In order for a search term to belong to a first come first serve type, the number of times that the search term appears in the search history must not exceed the second threshold value. Area 310 contains search terms that may be reserved with additional verification of association. In order for a search term to be categorized as a term that can be reserved with additional verification of association, the number of times that the search term appears in the search history must exceed the second threshold value but must not exceed the first threshold value.

Area 315 contains search terms that are generic and are excluded from registration. In order for a search term to be categorized as a generic term, the number of times that the search term appears in the search history must exceed the first threshold and the ratio of the number of times the search result was selected subsequent to receiving the search term to the number of times that the search term appears in the search history must not exceed the third threshold value. Area 320 contains search terms that are categorized as top term types and may be reserved by the user or entity that is recognized to be associated with the search term. In order for a search term to be categorized as a generic term, the number of times that the search term appears in the search history must exceed the first threshold value and the ratio of the number of times the search result was selected subsequent to receiving the search term to the number of times that the search term appears in the search history must exceed a third threshold value.

FIG. 4 conceptually illustrates an electronic system with which some implementations of the subject technology are implemented. Electronic system 400 can be a laptop computer, a desktop computer, smartphone, PDA, a tablet computer or any other sort of device 102, 104, and 106. Such an electronic system includes various types of computer readable media and interfaces for various other types of computer readable media. Electronic system 400 includes a bus 408, processing unit(s) 412, a system memory 404, a read-only memory (ROM) 410, a permanent storage device 402, an input device interface 414, an output device interface 406, and a network interface 416.

Bus 408 collectively represents all system, peripheral, and chipset buses that communicatively connect the numerous internal devices of electronic system 400. For instance, bus 408 communicatively connects processing unit(s) 412 with ROM 410, system memory 404, and permanent storage device 402.

From these various memory units, processing unit(s) 412 retrieves instructions to execute and data to process in order to execute the processes of the subject disclosure. The processing unit(s) can be a single processor or a multi-core processor in different implementations.

ROM 410 stores static data and instructions that are needed by processing unit(s) 412 and other modules of the electronic system. Permanent storage device 402, on the other hand, is a read-and-write memory device. This device is a non-volatile memory unit that stores instructions and data even when electronic system 400 is off. Some implementations of the subject disclosure use a mass-storage device (such as a magnetic or optical disk and its corresponding disk drive) as permanent storage device 402.

Other implementations use a removable storage device (such as a floppy disk, flash drive, and its corresponding disk drive) as permanent storage device 402. Like permanent storage device 402, system memory 404 is a read-and-write memory device. However, unlike storage device 402, system memory 404 is a volatile read-and-write memory, such a random access memory. System memory 404 stores some of the instructions and data that the processor needs at runtime. In some implementations, the processes of the subject disclosure are stored in system memory 404, permanent storage device 402, and/or ROM 410. From these various memory units, processing unit(s) 412 retrieves instructions to execute and data to process in order to execute the processes of some implementations.

Bus 408 also connects to input and output device interfaces 414 and 406. Input device interface 414 enables the user to communicate information and select commands to the electronic system. Input devices used with input device interface 414 include, for example, alphanumeric keyboards and pointing devices (also called “cursor control devices”). Output device interfaces 406 enables, for example, the display of images generated by the electronic system 400. Output devices used with output device interface 406 include, for example, printers and display devices, such as cathode ray tubes (CRT) or liquid crystal displays (LCD). Some implementations include devices such as a touchscreen that functions as both input and output devices.

Finally, as shown in FIG. 4, bus 408 also couples electronic system 400 to a network (not shown) through a network interface 416. In this manner, the computer can be a part of a network of computers (such as a local area network (“LAN”), a wide area network (“WAN”), or an Intranet, or a network of networks, such as the Internet. Any or all components of electronic system 400 can be used in conjunction with the subject disclosure.

These functions described above can be implemented in digital electronic circuitry, in computer software, firmware or hardware. The techniques can be implemented using one or more computer program products. Programmable processors and computers can be included in or packaged as mobile devices. The processes and logic flows can be performed by one or more programmable processors and by one or more programmable logic circuitry. General and special purpose computing devices and storage devices can be interconnected through communication networks.

Some implementations include electronic components, such as microprocessors, storage and memory that store computer program instructions in a machine-readable or computer-readable medium (alternatively referred to as computer-readable storage media, machine-readable media, or machine-readable storage media). Some examples of such computer-readable media include RAM, ROM, read-only compact discs (CD-ROM), recordable compact discs (CD-R), rewritable compact discs (CD-RW), read-only digital versatile discs (e.g., DVD-ROM, dual-layer DVD-ROM), a variety of recordable/rewritable DVDs (e.g., DVD-RAM, DVD-RW, DVD+RW, etc.), flash memory (e.g., SD cards, mini-SD cards, micro-SD cards, etc.), magnetic and/or solid state hard drives, read-only and recordable Blu-Ray® discs, ultra density optical discs, any other optical or magnetic media, and floppy disks. The computer-readable media can store a computer program that is executable by at least one processing unit and includes sets of instructions for performing various operations. Examples of computer programs or computer code include machine code, such as is produced by a compiler, and files including higher-level code that are executed by a computer, an electronic component, or a microprocessor using an interpreter.

While the above discussion primarily refers to microprocessor or multi-core processors that execute software, some implementations are performed by one or more integrated circuits, such as application specific integrated circuits (ASICs) or field programmable gate arrays (FPGAs). In some implementations, such integrated circuits execute instructions that are stored on the circuit itself.

As used in this specification and any claims of this application, the terms “computer”, “server”, “processor”, and “memory” all refer to electronic or other technological devices. These terms exclude people or groups of people. For the purposes of the specification, the terms display or displaying means displaying on an electronic device. As used in this specification and any claims of this application, the terms “computer readable medium” and “computer readable media” are entirely restricted to tangible, physical objects that store information in a form that is readable by a computer. These terms exclude any wireless signals, wired download signals, and any other ephemeral signals.

To provide for interaction with a user, implementations of the subject matter described in this specification can be implemented on a computer having a display device, e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user and a keyboard and a pointing device, e.g., a mouse or a trackball, by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, e.g., visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input. In addition, a computer can interact with a user by sending documents to and receiving documents from a device that is used by the user; for example, by sending web pages to a web browser on a user's electronic device in response to requests received from the web browser.

Embodiments of the subject matter described in this specification can be implemented in a computing system that includes a back end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front end component, e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the subject matter described in this specification, or any combination of one or more such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), an inter-network (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks).

The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. In some embodiments, a server transmits data (e.g., an HTML page) to an electronic device (e.g., for purposes of displaying data to and receiving user input from a user interacting with the electronic device). Data generated at the electronic device (e.g., a result of the user interaction) can be received from the electronic device at the server.

It is understood that any specific order or hierarchy of steps in the processes disclosed is an illustration of exemplary approaches. Based upon design preferences, it is understood that the specific order or hierarchy of steps in the processes may be rearranged, or that all illustrated steps be performed. Some of the steps may be performed simultaneously. For example, in certain circumstances, multitasking and parallel processing may be advantageous. Moreover, the separation of various system components in the embodiments described above should not be understood as requiring such separation in all embodiments, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.

The previous description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects. Thus, the claims are not intended to be limited to the aspects shown herein, but are to be accorded the full scope consistent with the language claims, wherein reference to an element in the singular is not intended to mean “one and only one” unless specifically so stated, but rather “one or more.” Unless specifically stated otherwise, the term “some” refers to one or more. Pronouns in the masculine (e.g., his) include the feminine and neuter gender (e.g., her and its) and vice versa. Headings and subheadings, if any, are used for convenience only and do not limit the subject disclosure.

A phrase such as an “aspect” does not imply that such aspect is essential to the subject technology or that such aspect applies to all configurations of the subject technology. A disclosure relating to an aspect may apply to all configurations, or one or more configurations. A phrase such as an aspect may refer to one or more aspects and vice versa. A phrase such as a “configuration” does not imply that such configuration is essential to the subject technology or that such configuration applies to all configurations of the subject technology. A disclosure relating to a configuration may apply to all configurations, or one or more configurations. A phrase such as a configuration may refer to one or more configurations and vice versa.
